Here are my modprobe settings for WinTV GO card (no FM). These are not necessarily optimal settings, but should get you started.

These settings are being asked in mailing lists and web forums all over again...

Not sure if "chroma_agc=1 pll=2" are needed.. I found them from some web posting. NOTE that WinTV Go comes in several varieties: you need to experiment type and tuner options.

Useful links I found:




And dont forget this important section from Jared's Mythtv on FC4 document:

http://wilsonet.com/mythtv/printer-friendly.php?SID&expandables=closed&ivtv=closed&pvr350out=closed#video [4]

Unlike the PVR-x50s, which mux audio in with the video stream into mpeg2 files, I needed an audio jumper cable from the sound out on the TV card to the line in on my sound card. This is all well and good for xawtv, but you need to make a few quick tweaks for use with MythTV. Open up your sound mixer (Fedora/Red Hat menu → Sound & Video → Volume Control) and mark the check boxes for Mute and Record for the Line In on your sound card. Now when you try xawtv, you'll get no sound, but when you fire up MythTV, everything will be gravy. Trust me. Note that ALSA in the 2.6 kernels has a snd-bt8x8 modules (or something like that) which works with *some* bttv cards to get audio into your system without need for an audio jumper cable, but I haven't tried it.

And relevant WinTV GO/bttv snippet from dmesg:

User Experiences

If you have this card, speak up! This is a good place to note your experiences - ease of install, what you like, what's not to like, etc.

- I have a WinTVGO w/FM. Works great with myth, but it uses the bttv module and the snd_bt87x module to get audio directly off the card. This is much better than using a sound card input. The page lists Iv Tv as the driver, but I thought that was only for the PVR series of cards. To clear up permissions problems with the module on Fedora, I've modified the mythbackend startup script with these three lines, before starting myth.

mknod /dev/video0 c 81 0 && chown mythtv /dev/video0 && chmod 600 /dev/video0
modprobe bttv
modprobe snd_bt87x
 - Scott Carlson

Scott: Could you explain how to utilize the bt878 sound coming off of the WinTV card without using a cable to go from audio out to line-in? -Michael Lynch

I have the WinTV Go Plus. Does it fall under this catagory? It has a remote also.
